Have you ever had the frustration of being stuck in bumper-to-bumper traffic on a hot summer day? Chances are that you have. Sure, it may be hot and humid outside, but you'd better believe that the temperatures under the hood of your truck are even worse. That's bad. And if it gets too hot, well, cross your fingers and hope you'll make it home. Why? Quite simply, because heat is the enemy of your truck's engine.

The cooling system in your truck is your engine's front line of defense when it comes to the ongoing battle against heat. If you properly maintain your truck's cooling system and take a few other preventative measures, you're ensuring that your engine won't experience the added stress of operating under extreme high temperatures. But how do you keep your truck's engine running cool under most normal driving conditions? Is there anything that you can do to prevent your truck from overheating?
